“…1. The C-C, C-O and C = O stretching bands are assigned to the vibrations centred at 1035 and 1217 cm − 1 respectively depicting the presence of carbon content in the sample [25]. While, the absorption bands at 520 and 675 cm − 1 are attributed to the Fe-CO and Fe-O symmetric stretching vibrations [26][27].…”

This article reports the fluorometric detection of toxic hexavalent chromium Cr (VI)) in wastewater and Cr (VI) contaminated living cells using in-situ grown carbon quantum dots into the goethite (α-FeOOH) nano-matrix. The synthesized nano-hybrid shows enormous potential in determining the chromium contamination levels in various types of water samples. This selective fluorometric probe is enormously sensitive (LOD 81nM) towards hexavalent chromium, which makes it a dedicated chromium sensor. Moreover, the sensing mechanism has been assessed using Stern-Volmer’s equation and fluorescence lifetime experiments showing the simultaneous occurrence of photoinduced electron transfer and inner filter effect. This chromium sensor has also been employed to assess the contamination level in real-life industrial wastewater. The performance of this probe in real-life wastewater sample is quite commendable. Further, this biocompatible fluorometric probe has been used to demonstrate the in-vitro sensing of Cr (VI) in HeLa cells. The rapid detection mechanism of hexavalent chromium in living cells has been validated using theoretical docking simulations. Henceforth, this fluorometric sensor material could open new avenues not only in wastewater monitoring but also in biomedical applications.
